11 Myths About Formal Verification

11 Myths About Formal Verification | Test and Measurement Equipment by MATsolutions | Scoop.it

"Formal verification, which uses mathematical analysis rather than simulation tests, has been available in commercial EDA tools for more than 20 years and in academia much longer. As with many new technologies, initial adoption was slow and limited to companies who had in-house formal experts. This has changed dramatically in the last dozen years or so. Almost every chip-development team makes some use of formal tools, and the market continues to grow. Nevertheless, some myths about formal persist, and they may still be deterring some engineers who could benefit from it. It’s time for the truth to be told."

MATsolutions's insight:

Don't believe everything you may have heard about Formal Verification - especially if it is keeping you from using it. It can be very beneficial to use, so before avoiding it, read up on the myths and get to know the benefits.

EMI emissions testing: peak, quasi-peak, and average measurements

EMI emissions testing is critical to bringing a product to market. Most electrical and electronic products require regulatory compliance testing, which must be performed in an approved test lab. Such testing can be expensive, especially if the product fails. A failed test can result in lost time to market and cost overruns. 

To minimize unwanted trips to the test lab prior to compliance tests, you can measure EMI emissions from your product. Not only will this increase your chances of passing emission compliance testing the first time, it can help you identify potential issues early on and reduce the need for last-minute product redesigns. There are several measurements you can do using a spectrum analyzer or EMI receiver.

MATsolutions's insight:

To measure EMI emissions, your spectrum analyzer must have the correct software to support quasi-peak, peak and average detection. View our spectrum analyzers here: http://srenew.al/191829

5G Will Take Some Rethinking to Scale

Before we see 5G networks and handsets, semiconductor fabs will need to change the way that they process wafers, test engineers will have to figure out how to test, and handset designers will have to figure out how to track steered beams as people move. On top of these and other problems, wireless products will have to sell for prices close to current levels. These were the takeaways from the 5G Summit at the 2018 International Microwave Symposium (IMS). 

MATsolutions's insight:

There are some processes that still need to be considered for 5G to come to life. This article explains the discussions from the  5G Summit at the 2018 International Microwave Symposium (IMS).

Will 5G be reliable?

In May of this year, I attended an Emerging Technologies Workshop as part of the IEEE ComSoc International Communications Quality and Reliability Conference. During this workshop, I had the opportunity to present some of National Instruments' work in the 5G space, and to learn how others view 5G’s impact. In particular, I was curious to hear more about reliability as a key performance objective of 5G and the specific use cases targeted by the 3GPP. 

MATsolutions's insight:

The deployment of 5G will likely be longer than LTE because the standard has so many variations and configurations. See what the deployment will look like and what will need to be done to ensure 5G will be reliable.

Working with waveforms in mixed-domain oscilloscopes

Working with waveforms in mixed-domain oscilloscopes | Test and Measurement Equipment by MATsolutions | Scoop.it
Waveform generators generally contain a library of common waveforms, which can be individually accessed and displayed by running a BNC cable to an active analog channel input in an oscilloscope. Most oscilloscopes have, available as an option, an internal arbitrary function generator (AFG), which permits the user to create an endless variety of waveforms and display and save them to internal memory or to an external medium. These internal AFGs also have a selection of pre-made waveforms, although not as extensive as in the stand-alone bench-type waveform generators.

Making Power Supply Transient Recovery Time Measurements with Digital Multimeters | Tektronix

Making Power Supply Transient Recovery Time Measurements with Digital Multimeters | Tektronix | Test and Measurement Equipment by MATsolutions | Scoop.it
By Josh Brown
Transient recovery time, simply put, is duration of time needed for a power supply to return to its set level after a load is applied. Those of us who do not design power supplies have a tendency to take this for granted, applying whatever loading circuitry we are working on until, perhaps, the supply performance degrades to the point it impacts our own work. Power supplies are a little like people, if you ask more from them than they are capable of, they won’t perform like you might expect.
MATsolutions's insight:

Transient recovery time is important to measure to make sure you are not causing the equipment to underperform. 

 

This post provides insight on how to measure transient recovery time by walking through the method using the LM25088MH-1EVL evaluation board from Texas Instruments.

Wi-Fi Testing Now Includes Performance

Just because your Wi-Fi router complies with 802.11 standards and has passed interoperability tests doesn't mean that you'll be happy with its performance. That's why the Broadband Forum is developing WT-398. When approved, WT-398 will specify tests for Wi-Fi router performance. In parallel with that document's development, the University of New Hampshire Interoperability Lab (UNH-IOL) has announced testing services for Wi-Fi performance. 

The impetus for WT-398, which is not yet available publicly, came from service providers that deliver internet access and provide either Wi-Fi routers that are either integrated with gateways or are separate units. "Service providers found themselves providing support for home networking issues," said UNH-IOL senior engineer Lincoln Lavoie in an interview with EE Times. "The problem stems from so many devices now being connected to a home router." 

MATsolutions's insight:

"In addition to fairness and quality of service, test plans will cover interference from other devices such as ZigBee and Bluetooth that use the same unlicensed 2.4 GHz channels as Wi-Fi. Plus, there is the issue of many 802.11 routers covering any given area."

 

The WT-398 standard is up for a vote and the release is expected by the end of June.
